sLIcINe MACHINE.

Application filed. September 8, 1928. Serial No. 304,764.

My invention relates to a slicing machine having a rotary knife andrelates particularly to a knife guard for such slicing machine. Oneobject of my invention is to provide a guard which shall cover theforward side of theexposed cutting arc of a rotary knife. Another objectis the provision of such a guard which may be a plied to a work carriagetraveling across the face of said knife. Another object is the provisionof such a guard which shall cover or guard the cutting edge of the knifewhen the carriage reaches the end of its cutting excursion and when thework has been carried past the cutting edge of the knife. Other objectswill appear from time to time in the course of the specification andclaims. I illustrate my invention more or less diagrammatically in theaccompanying drawings, wherein- Figure 1 is a front elevation; and

Figure 2 is a section on the line 2-2 of Figure 1. Like parts areindicated by like symbols throughout the specification and drawings.

A generally indicates any suitable base upon which is mounted the rotaryknife A which may be actuated through the pulley A arid belt A from thedriving pulley A on a shaft A which may be rotated for example by anelectric motor or any other suitable prime motor, not herein shown. Itwill be observed from the drawings that the knife A lies in a generallyvertical plane,

I its axis of rotation being horizontal. This axis however is slightlytilted, in the horizontal plane, to throw the cutting edge or arc of theknife forwardly, as shown in Figure 2, the plane of the knife heing thussomewhat inclined to the plane of the forward guard plate B. l

C C indicate tracks along which runs the meat carriage 'eneral-lyindicated as (F, which includes tlie work. supporting surface C and theupstanding fiange (3 along one edge thereof. .C is any suitable handlewhereby the work supporting carriage may be'reciprocated across thecutting plane of the knife.

D indicates a gauge plate mounted on the support D which may movedtoward and away from the cutting plane of the knife as by rotation ofthe handle D E indicatesa guard member, herein shown as roughly arcuatein shape. It is secured by means of the flange E and the screws E to theupstanding flange 0 of the meat supporting surface C In order that thework may be cut it is necessary that the cutting arc of. the knife beexposed, as shown for example in Figure 1. However it is desirable thatthis cutting are be protected or covered when the necessity for exposingit has passed. lVhen the carriage is in the full supporting carriage is'carried to the dotted line position of-Figure 1, then the guard Eoverlies and masks the cutting are. As shown in Figure 2 the edge of thegauge plate masks the cutting are from the rear and the are E masks itfrom the front and when the carriage is in dotted line position it ispractically impossible for an operator to cut his hand unless. heactually inserts his fingers between gauge plate and guard, a mostunlikely performance.

I claim:

1. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member guided across theface of the knife, a guard adapted to mask the cutting edge of the knifefrom the work support side, and means for positioning said guard inoperative position at the termination of the cutting excun sion of thework support.

2. In association with a slicing machine including a rotary knife andmeans for retating it and a work supporting member guided across theface of the knife, a guard v adapted to mask the cutting edge the knife,and means'for positioning said guard in operative position at thetermination of the cutting excursion of the work support.

3. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member guided acrossthe faceof the knife, a guard mounted upon said work supporting member andadapted to mask the cutting edge of the knife ,when the work supportingmember has passed across such cutting edge.

4. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member and means for guidingit across the face of the knife, a guard mounted upon and projectingupwardly from said work supporting meme ber, adapted to mask the cuttingedge of the knife when the work supporting member has been moved acrosssaid cutting edge.

5. In association with a slicing machine including a rotary knife andmeans for rotating it and a-work supportin member and means for guidingit across t e face of the knife, a guard mounted upon and projectingupwardly from said work supporting member, adapted to mask the side ofthe cutting edge toward the work supporting member when the worksupporting member has been moved across said cutting edge.

6. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member and means for guidingit across the face of the knife, a'guard associated with said worksupporting member, adapted to mask the .side of the cutting edge of theknife toward the work supporting member when the work supporting memberhas been moved across said cutting edge.

7. In association with a slicing machine including a rotary knife andmeans for ro-.

tating it and a work supporting member and means for guiding it acrossthe face of the knife, a guard associated with said work supportingmember, adaptedto mask the side of the cutting edge of the knife toward1nclud1ng a rotary knife and means for rothe work supporting member whenthe work supporting member has been moved across sald'cutting edge, saidguard including a plate positioned upon and movable with said worksupporting member, lyingin a plane generally parallel with the path ofmovement of the work supporting member and in front of the knife edge.

8. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member and means for guidingit across the face of the knife, a guard, mounted upon said worksupporting member, adapted to mask the cutting edge of the knife.

9. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member and means for guidingit across the face of the knife, a guard, mounted upon said worksupporting member, adapted to mask the cutting edge of the knife, saidguard being positioned on the same side of the knife edge as the worksupporting member.

10. In association with a slicing machine including a rotary knife andmeans for rotating it and a work supporting member and means forguidingit across the face of the knife, a guard associated with said worksupporting member, adapted to mask the side of the cutting edge of theknife toward 'the work supporting member when the work supporting memberhas been moved across said cutting edge, said guard including a platepositioned upon and movable with said work supporting member, said plateextend ing outwardly beyond the peripheryof theknife, when in operativeposition. v

11. In association wlth a slicing machine including a rotary knife andmeans for rosupporting member, adapted to mask the side of the cuttingedge of the knife toward the work supporting member when the worksupporting member has been moved across said cutting edge, said guardincluding a plate positioned upon and movable with said work supportingmember, said plateextending outwardly beyond the periphery of theknife,'when the work supporting member is at .the termination of itsworking stroke.

-12. In association with a slicing machine including a rotary knife andmeans for rotating it and a worksupporting member movable across theface of the knife, a guard, mounted on the edge of said supportingmember remote from the knife when the supporting member is in initialposition, such guard being adapted to overlie and mask the cutting edgeof the knife from the work support side at the termination of thecutting excursion of the work support.
